FIG. 2A is a method flowchart of an interface interaction method according to an exemplary embodiment of the present disclosure. The method may be applied to the electronic device shown in FIG. 1. As shown in FIG. 2A, the interface interaction method may include the following steps.

Step 201: Control a display component to display at least two interfaces, where the at least two interfaces belong to different interface groups.

Each interface group includes at least one interface, and only one interface in each interface group is displayed at a time.

In this embodiment of the present disclosure, the interfaces displayed by the display component of the electronic device may be interfaces based on an augmented reality technology or a virtual reality technology. For example, the at least two interfaces may be virtual interfaces displayed on a transmissive projection display or a perspective display apparatus based on a video synthesis technology. The at least two interfaces may be arranged in a linear sequence. For example, the at least two interfaces may be arranged in a left-to-right sequence, or the at least two interfaces may be arranged in a top-to-bottom sequence. Each displayed interface belongs to a different interface group, that is, only a front interface in an interface group is completely visible, and another interface is partly or completely blocked by the front interface. The electronic device displays by default a first interface in a direction of a front-view sightline of a user, and the first interface that faces the front-view sightline of the user is in an active state when the foregoing at least two interfaces are displayed for the first time. The interface in the active state may have a special display effect, such as an enlarged shape, a highlighted outline, outer glow, or projection. In practical application, limited by a factor such as a size of a display or a display apparatus, a user may only see an interface in a specific view range in front of the user. In this disclosed embodiment, the interface that faces the front-view sightline of the user may be an interface that intersects with the front-view sightline of the user. For the front view described in this embodiment of the present disclosure, a reference object is the user head, and is not related to another body part of a user, that is, the foregoing front view direction is in front of a user face.

In practical application, in the foregoing at least two interfaces, an interface group corresponding to a more centrally located interface may display relatively important content, and an interface group corresponding to a more edge-located interface may display relatively less important content. Similarly, in a same interface group, a front interface may display relatively important content, and a following interface may display relatively less important content. An interface closer to the front displays more important content.

For example, the at least two interfaces are displayed in a left-to-right sequence. Referring to FIG. 2B, FIG. 2B shows a schematic diagram of an interface layout provided by this embodiment of the present disclosure. As shown in FIG. 2B, a center of a user head is used as an origin to create a space coordinate system. The right side of a user is the positive direction of the x-axis, the upper side is the positive direction of the y-axis, and the front is the positive direction of the z-axis. Five interfaces shown in FIG. 2B are displayed in specified positions around the user head in a left-to-right sequence. The five interfaces are an interface A01, an interface B01, an interface C01, an interface D01, and an interface E01 respectively. Optionally, the interface layout may further include a function specific interface (not shown), such as an exit interface. The function specific interface may be displayed behind the user head.

In FIG. 2B, the interface C01 belongs to an interface group C. The interface group C further includes an interface C02 to an interface C06, and the interface C02 to the interface C06 are sequentially arranged behind the interface C01 in the positive direction of the z-axis. Correspondingly, the interface A01 belongs to an interface group A, the interface B01 belongs to an interface group B, the interface D01 belongs to an interface group D, and the interface E01 belongs to an interface group E. Other interfaces included in the interface groups A, B, D, and E are not shown in the figure.

In FIG. 2B, the interface C01 that faces a front-view sightline of the user is in an active state. Under the interface C01, there are control interfaces of the interface C01, an interface C01-1, an interface C01-2, an interface C01-3, an interface C01-4, and an interface C01-5. Each control interface corresponds to one control function, such as confirming, cancelling, adding, deleting, editing, saving, or favorites. In an initial state, the control interfaces (the interface C01-1, the interface C01-2, the interface C01-3, the interface C01-4, and the interface C01-5) of the interface C01 are hidden and not directly displayed.

In FIG. 2B, the front-view sightline of the user faces the interface C01, the front-view sightline of the user is S, and central coordinates of the interface C01 are (x₁, y₁, z₁). In this case, C01 is in the active state.

Step 201 may be implemented by the processor 110 in the electronic device 100 using the execution module 1543.

Step 202: Obtain rotation parameters of a user head, where the rotation parameters include a rotation direction, a rotation angle, and a rotation angular acceleration.

The electronic device may obtain the rotation parameters of the user head using a sensor component worn on the user head.

Step 202 may be implemented by the processor 110 in the electronic device 100 by executing the sensing parameter obtaining module 1541.

Step 203: Determine an interaction instruction according to the obtained rotation parameters and a preset instruction determining rule.

In this embodiment of the present disclosure, the electronic device may determine different interaction instructions according to different rotation directions and different rotation angular accelerations of the user head as well as the preset instruction determining rule. For example, referring to FIG. 2C, FIG. 2C shows a method flowchart of an interaction instruction determining method according to this embodiment of the present disclosure. As shown in FIG. 2C, the interaction instruction determining method may include the following steps.

Step 203 a: Obtain a rotation angle r of the user head in the vertical direction, and a rotation angle t of the user head in the horizontal direction.

After obtaining the rotation parameters of the user head, the electronic device may divide, according to the vertical direction and the horizontal direction, the rotation parameters into two groups, a rotation angle and an angular acceleration in the vertical direction, and a rotation angle and an angular acceleration in the horizontal direction.

The interface layout shown in FIG. 2B is used as an example. The electronic device may divide the rotation parameters of the user head into a rotation angle and an angular acceleration on the yz plane (namely the vertical direction), and a rotation angle and an angular acceleration on the xz plane (namely the horizontal direction).

Step 203 b: Determine whether r>t is true, proceed to step 203 c if r>t is true, and proceed to step 203 d if r>t is false.

An interaction instruction may be generated according to the rotation angle and the angular acceleration of the user head in the vertical direction if the rotation angle r of the user head in the vertical direction is greater than the rotation angle t of the user head in the horizontal direction, indicating a relatively large rotation angle of the user head in the vertical direction. An interaction instruction may be generated according to the rotation angle and the angular acceleration of the user head in the horizontal direction if the rotation angle r of the user head in the vertical direction is not greater than the rotation angle t of the user head in the horizontal direction, indicating a relatively large rotation angle of the user head in the horizontal direction. Interaction instructions generated according to rotation angles and angular accelerations in different directions have different interaction effects.

Step 203 c: Generate a first-type interaction instruction according to r and a rotation angular acceleration a of the user head in the vertical direction.

A manner of generating the first-type interaction instruction according to r and the rotation angular acceleration a of the user head in the vertical direction may include the following types.

1. A first interaction instruction is generated when the user head rotates upward, |r|ε[A₁, B₁], and |a|<a₁. The first interaction instruction is used to instruct the display component to replace the first interface with a second interface, the second interface is an interface that is in an interface group to which the first interface belongs and that follows the first interface, A₁, B₁, and a₁ are preset values, 0<A₁<B₁, and 0<a₁.

Further, the interface layout shown in FIG. 2B is used as an example. Referring to FIG. 2D to FIG. 2G, FIG. 2D to FIG. 2G show schematic diagrams for replacing an interface. When the electronic device detects that the user head rotates upward, a rotation angle is between A₁ and B₁, and a rotation angular acceleration is less than a threshold, it is considered that the user performs an operation of replacing the current active interface by rotating the head. In this case, the electronic device generates the first interaction instruction. When the electronic device executes the instruction, the interface C01 is first deactivated and then moves behind the interface C06, and at the same time, the interface C02 moves in the negative direction of the z-axis until central coordinates of the interface C02 change to (x₁, y₁, z₁). Afterward, the interface C02 is activated.

2. A second interaction instruction is generated when the user head rotates downward, |r|ε[A₂, B₂], and |a|<a₂. The second interaction instruction is used to instruct the display component to display at least one control interface of the first interface, A₂, B₂, and a₂ are preset values, 0<A₂<B₂, and 0<a₂.

Optionally, each control interface corresponds to one control operation. After the second interaction instruction is generated, the electronic device may further determine a target control interface, where the target control interface is a control interface that faces a front-view sightline of the user, control the target control interface to enter an active state, detect whether a duration that the target control interface remains in the active state is greater than a predetermined duration, and generate a third interaction instruction if a detection result is that the duration that the target control interface remains in the active state is greater than the predetermined duration. The third interaction instruction is used to instruct the display component to display an execution result after a control operation corresponding to the target control interface is performed on the first interface.

The electronic device may obtain, by means of calculation according to a front-view sightline of the user before the head rotates and the rotation parameters of the user head, the front-view sightline of the user after the head rotates.

The interface layout shown in FIG. 2B is used as an example. Referring to FIG. 2H, FIG. 2H shows a schematic diagram for displaying a control interface. When the electronic device detects that the user head rotates downward, a rotation angle is between A₂ and B₂, and a rotation angular acceleration is less than a threshold, it is considered that the user performs an operation of triggering a control interface by rotating the head. In this case, the electronic device generates the second interaction instruction. When the electronic device executes the instruction, the control interfaces (the interface C01-1, the interface C01-2, the interface C01-3, the interface C01-4, and the interface C01-5) are displayed under the interface C01, the interface C01 is deactivated, and the electronic device determines that the interface C01-2 (target control interface) that faces a front-view sightline of the user is activated. The user may further switch, by rotating the head in the horizontal or vertical direction, a control interface that faces a front-view sightline. Further, the electronic device generates the third interaction instruction corresponding to the control interface C01-2 when detecting that a duration that the interface C01-2 remains in the active state is greater than a predetermined duration (such as 2 seconds). After the electronic device executes the third interaction instruction, the display component displays a result after a control operation corresponding to the interface C01-2 is performed on the interface C01.

In another possible implementation manner, the first interaction instruction and the second interaction instruction may correspond to reverse rotation directions. For example, when a rotation direction of the user head is downward, |r|ε[A₁, B₁], and |a|<a₁, the first interaction instruction is generated, and the interface C01 is switched to the interface C02, when a rotation direction of the user head is upward, |r|ε[A₂, B₂], and |a|<a₂, the second interaction instruction is generated, and at least one control interface is displayed above the interface C01.

In practical application, the electronic device may not detect a rotation angle of the user head in the vertical direction but detect only a rotation angular acceleration of the user head in the vertical direction when the first interaction instruction and the second interaction instruction are generated. For example, the first interaction instruction is generated when the user head rotates upward and |a|<a₁, or the second interaction instruction is generated when the user head rotates downward and |a|<a₂.

3. When the user head rotates upward and |a|≧a₃, or when the user head rotates downward and |a|≧a₄, a fourth interaction instruction is generated. The fourth interaction instruction is used to instruct the display component to control the at least one interface to rotate around the user head according to the rotation parameters of the user head.

It should be noted that, when the electronic device supports generation of the first interaction instruction, the second interaction instruction, and the fourth interaction instruction, a₃ needs to be greater than or equal to a₁, a₄ needs to be greater than or equal to a₂, and values of a₁ and a₂ may be the same or different.

The interface layout shown in FIG. 2B is used as an example. Referring to FIG. 2I, FIG. 2I shows a schematic diagram for rotating an interface. The electronic device generates the fourth interaction instruction when the user head rotates upward and a rotation angular acceleration reaches or exceeds a threshold. When the electronic device executes the instruction, the at least one interface (only the interface C01 is shown in FIG. 2I) as a whole follows the user head into upward rotation, with the user head at the center. Rotation parameters of the at least one interface are consistent with the rotation parameters of the user head in order to ensure that a front-view sightline of the user is located at the center of the interface C01. Alternatively, in another possible implementation manner, rotation parameters of the at least one interface may be consistent only with rotation parameters of the user head in the vertical direction.

Similarly, when the user head rotates downward and a rotation angular acceleration reaches or exceeds a threshold, the at least one interface also follows the user head into rotation, with the user head at the center. Details are described herein.

In another possible implementation manner, a fourth interaction instruction is generated when the user head rotates upward, |r|>B₁, and |a|<a₁, or when the user head rotates downward, |r|>B₂, and |a|<a₂. That is, despite a relatively small angular acceleration, the at least one interface may be controlled to follow the user head into rotation, with the user head at the center when an upward or downward rotation angle of the user head exceeds a preset threshold.

Further, FIG. 2D to FIG. 2I are used as an example. Referring to FIG. 2J, FIG. 2J shows a flowchart of a first-type interaction instruction generating method, and shows a possible implementation procedure of step 203 c. For example, values of a₁, a₂, a₃, and a₄ are the same. As shown in FIG. 2J, the first-type interaction instruction generating method may include the following steps.

Step 203 c 1: Determine whether |a|<a₁ is true, proceed to step 203 c 2 if |a|<a₁ is true, and proceed to step 203 c 8 if |a|<a₁ is false.

Step 203 c 2: Determine whether the user head rotates upward, proceed to step 203 c 3 if the user head rotates upward, and proceed to step 203 c 5 if the user head does not rotate upward.

Step 203 c 3: Detect a magnitude relationship between |r|A₁, and B₁.

Step 203 c 4: Keep a current interface unchanged when 0<|r|<A₁, or generate a first interaction instruction when A₁≦|r|<B₁, or generate a fourth interaction instruction when |r|>B₁.

Step 203 c 5: Detect a magnitude relationship between |r|, A₂, and B₂.

Step 203 c 6: Keep a current interface unchanged when 0<|r|<A₂, or generate a second interaction instruction when A₂≦|r|≦B₂, or generate a fourth interaction instruction when |r|>B₂.

Step 203 c 7: After the second interaction instruction is generated, when it is detected that a duration that a target control interface remains in an active state is greater than a predetermined duration, generate a third interaction instruction.

Step 203 c 8: Generate a fourth interaction instruction.

Step 203 d: Generate a second-type interaction instruction according to t and a rotation angular acceleration a′ of the user head in the horizontal direction.

Similar to step 203 c, a manner of generating the second-type interaction instruction according to t and the rotation angular acceleration a′ of the user head in the horizontal direction may include the following several types.

1. When |a′|<a₅, a third interface that faces a front-view sightline of the user is determined, and a fifth interaction instruction is generated. The third interface is an interface in the at least two interfaces that is located on the left or right of the first interface. The fifth interaction instruction is used to instruct the display component to switch an interface in an active state from the first interface to the third interface, a₅ is a preset value, and 0<a₅.

The interface layout shown in FIG. 2B is used as an example. Referring to FIG. 2K, FIG. 2K shows a schematic diagram for switching an active interface. When the electronic device detects that the user rotates to the right, and a rotation angular acceleration is less than a threshold, it is considered that the user intends to switch a current active interface to another interface on the right of the current interface. When a rotation angle of the user head is less than an angle C, it is considered that an interface that faces the front-view sightline of the user is still the interface C01. In this case, the interface C01 remains in an active state. When a rotation angle of the user head is greater than the angle C and reaches an angle D, it is considered that the interface that faces the front-view sightline of the user changes to the interface D01. In this case, the fifth interaction instruction is generated. When the electronic device executes the instruction, the interface C01 is deactivated, and at the same time, the interface D01 is activated. In this case, operation logic of the interface D01 is similar to that of step 203 c, and details are not described herein. When the user continues to rotate the head to the right at a relatively small angular acceleration, and the interface that faces the front-view sightline of the user changes to the interface E01, the interface D01 is deactivated, and at the same time, the interface E01 is activated. Similarly, it is considered that the user intends to switch a current active interface to another interface on the left of the current interface when the electronic device detects that the user head rotates to the left, and a rotation angular acceleration is less than a threshold.

2. When |a′|<a₆, a front-view sightline of the user does not face any interface, and no other interface in the at least two interfaces exists in the horizontal direction in which the user head rotates, a sixth interaction instruction is generated. The sixth interaction instruction is used to instruct the display component to display a functional interface except the at least two interfaces.

The schematic diagram for switching an active interface shown in FIG. 2K is further used as an example. Based on FIG. 2K, after the interface E01 is activated, the electronic device generates the sixth interaction instruction if the user continues to rotate the head to the right at a relatively small angular acceleration, and there is no another interface in a direction of the front-view sightline of the user. After the electronic device executes the sixth interaction instruction, the function specific interface that was originally located behind the user head is displayed in the direction of the front-view sightline of the user, and at the same time, the interface A01 to the interface E01 move behind the user head. After the user keeps the head still for a period of time, the electronic device executes a function corresponding to the function specific interface, such as exiting an interface display state.

Optionally, the user may enter the interface display state again by rotating the head, that is, step 201 is triggered again. For example, step 201 is triggered when the electronic device detects, according to the rotation parameters of the user head, that the user rotates the head back and forth in the horizontal or vertical direction at least twice.

3. A seventh interaction instruction is generated when |a′|≧a₇. The seventh interaction instruction is used to instruct the display component to control the at least one interface to rotate around the user head according to the rotation parameters of the user head.

For example, the electronic device generates the seventh interaction instruction when the user head rotates to the left or right, and a rotation angular acceleration reaches or exceeds a threshold. When the electronic device executes the instruction, the at least one interface as a whole follows the user head into upward rotation, with the user head at the center. Rotation parameters of the at least one interface are consistent with the rotation parameters of the user head in order to ensure that a front-view sightline of the user is located at the center of the interface C01. Alternatively, in another possible implementation manner, rotation parameters of the at least one interface may be consistent only with rotation parameters of the user head in the horizontal direction.

It should be noted that, values of a₅, a₆, and a₇ may be the same when the electronic device supports generation of the fifth, the sixth, and the seventh interaction instructions.

Further, FIG. 2K is used as an example. Referring to FIG. 2L, FIG. 2L shows a flowchart of a second-type interaction instruction generating method, and shows a possible implementation procedure of step 203 d. For example, values of a₅, a₆, and a₇ are the same. As shown in FIG. 2L, the second-type interaction instruction generating method may include the following steps.

Step 203 d 1: Determine whether |a′|<a₅ is true, proceed to step 203 d 2 if |a′|<a₅ is true, and proceed to step 203 d 7 if |a′|<a₅ is false.

Step 203 d 2: Determine whether there is an interface that faces a front-view sightline of the user, proceed to step 203 d 3 if there is an interface that faces a front-view sightline of the user, and proceed to step 203 d 5 if there is no interface that faces a front-view sightline of the user.

Step 203 d 3: Detect whether the interface that currently faces the front-view sightline of the user is a third interface on the left or right of a first interface.

Step 203 d 4: Generate a fifth interaction instruction if the interface that currently faces the front-view sightline of the user is the third interface.

Keep the current interface unchanged if the interface that currently faces the front-view sightline of the user is still the first interface.

Step 203 d 5: Detect whether another interface in the at least two interfaces exists in the horizontal direction in which the user head rotates.

Step 203 d 6: Generate a sixth interaction instruction if no other interface exists on the side of the horizontal direction in which the user head rotates.

Step 203 d 7: Generate a seventh interaction instruction.

Step 203 may be implemented by the processor 110 in the electronic device 100 by executing the instruction determining module 1542.

Step 204: Execute the determined interaction instruction to implement interaction control of the interfaces displayed by the display component.

The interface layout shown in FIG. 2B is used as an example. After the electronic device executes the interaction instruction generated in step 203, an interaction effect described in step 203 c or step 203 d may be implemented, and details are not described herein.

Step 204 may be implemented by the processor 110 in the electronic device 100 using the execution module 1543.

In conclusion, in the method described in this embodiment of the present disclosure, rotation parameters such as a rotation direction, a rotation angle, and a rotation angular acceleration of a user head are obtained, an interaction instruction is determined with reference to the rotation parameters and a preset instruction determining rule, and the determined interaction instruction is executed to implement interaction control of interfaces displayed by a display component. A method for actively interacting with a virtual interface only by rotating a user head is provided, expanding a virtual interface interaction manner, and improving user experience.

In addition, in the method described in this embodiment of the present disclosure, a user only needs to control a head rotation angle and an angular acceleration to implement an interaction operation with an interface, and may browse information in a natural interaction manner without the aid of another special device or a hand movement, thereby achieving an effect of a simplified user operation.

In addition, in the method described in this embodiment of the present disclosure, different interfaces belonging to multiple interface groups are displayed around and in front of the user head, and each interface may be switched in a corresponding interface group to implement a well-ordered arrangement of massive information.

In practical application, the at least one interface may be arranged in a top-to-bottom sequence, and operation logic may be similar to the operation logic in the foregoing embodiment corresponding to the FIGS. 2A-2L. For example, when a horizontal rotation angle of a user head is relatively large, the first interaction instruction, the second interaction instruction, or the fourth interaction instruction is generated, or the fifth interaction instruction, the sixth interaction instruction, or the seventh interaction instruction is generated when a vertical rotation angle of a user head is relatively large.
